Device and method for virtualizing an image sensor

Abstract

A method virtualizes an image sensor. The method comprises selecting one of at least two portions of a filter to use as a function of a mode of operation. The method comprises capturing an image using the selected one of the at least two portions. The method comprises executing a functionality using data extracted from the image. The functionality corresponds to the mode of operation.

1. A method, comprising:
 selecting one of at least two portions of a filter to use as a function of a mode of operation, each of the at least two portions of the filter occupying a respective area of the filter and having a part of a total resolution corresponding to a percentage that the respective area occupies on the filter; 
 capturing an image using the selected one of the at least two portions; and 
 executing a functionality using data extracted from the image, the functionality corresponding to the mode of operation. 
 
     
     
       2. The method of  claim 1 , wherein the plurality of modes of operation includes at least taking a picture and scanning a barcode. 
     
     
       3. The method of  claim 2 , wherein a first portion of the at least two portions is used for taking the picture and a second portion of the at least two portions is used for scanning the barcode. 
     
     
       4. The method of  claim 1 , wherein a resolution of the image is a function of the selected one of the at least two portions of the filter. 
     
     
       5. The method of  claim 1 , wherein the filter includes four quadrants. 
     
     
       6. The method of  claim 5 , wherein a first quadrant is a Bayer filter, a second quadrant is a panchromatic filter, and each of a third quadrant and a fourth quadrant is one of an infrared filter, an ultraviolet filter, and a mixture of the Bayer filter and the panchromatic filter. 
     
     
       7. The method of  claim 5 , wherein the filter has a two megapixel resolution. 
     
     
       8. The method of  claim 7 , wherein each quadrant has a half megapixel resolution. 
     
     
       9. A device, comprising:
 a filter including at least two portions, a selection of one of the at least two portions is a function of a mode of operation of the device, each of the at least two portions of the filter occupying a respective area of the filter and having a part of a total resolution corresponding to a percentage that the respective area occupies on the filter; and 
 a data acquisition device disposed behind the filter capturing an image using the selected one of the at least two portions. 
 
     
     
       10. The device of  claim 9 , wherein the plurality of modes of operation includes at least taking a picture and scanning a barcode. 
     
     
       11. The device of  claim 10 , wherein a first portion of the at least two portions is used for taking the picture and a second portion of the at least two portions is used for scanning the barcode. 
     
     
       12. The device of  claim 9 , wherein a resolution of the image is a function of the selected one of the at least two portions of the filter. 
     
     
       13. The device of  claim 9 , wherein the filter includes four quadrants. 
     
     
       14. The device of  claim 13 , wherein a first quadrant is a Bayer filter, a second quadrant is a panchromatic filter, and each of a third quadrant and a fourth quadrant is one of an infrared filter, an ultraviolet filter, and a mixture of the Bayer filter and the panchromatic filter. 
     
     
       15. The device of  claim 13 , wherein the filter has a two megapixel resolution. 
     
     
       16. The device of  claim 15 , wherein each quadrant as a half megapixel resolution. 
     
     
       17. A device, comprising:
 a filtering means for capturing a type of data, the filtering means including at least two portions, a selection of one of the at least two portions is a function of a mode of operation of the device, each of the at least two portions of the filtering means occupying a respective area of the filter and having a part of a total resolution corresponding to a percentage that the respective area occupies on the filtering means; and 
 a data acquisition means disposed behind the filtering means for capturing an image using the selected one of the at least two portions, the image being captured with the type of data.
